GAP FOR MILK BOTTLES.

Application filed April 21, 1924. Serial No. 707,822.

T 0 all who-m it may concern:

Be it known that I, MICHAEL J. LYONS, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Caps for Milk Bottles, of which the following is a specification.

My invention relates to caps for milk bottles and its object is to provide a cap which may be quickly applied to and removed from a milk bottle; which will efliciently seal the bottle; which will meet all sanitary conditions and which may be produced at low cost.

These objects, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawing in which Figure 1 is a fragmentary central section through a bottle and a cap constructed in accordance with my invention, and

Figure 2 a view similar to Figure 1 illustrating the cap in the sealing position.

Referring to the drawing, 1 indicates the neck of an ordinary milk bottle having an annular internal shoulder 2 and a wall 3 extending above the shoulder. My improved cap 4: rests on the shoulder and consists of a disk 5, of upwardly curved crosssection, having its center pressed into a conical boss 6 adapted to receive a counter-sunk head 7 of a securing screw 8 screwed into a knob 9 having a counter-sunk lower surface 10 engaging the upper side of the conical boss. Knob 9 is used for applying disk 5 to and removing it from the bottle. The knob is preferably connected to the bottle by a chain 11 and a wire band 12 secured around the neck of the bottle. The diameter of the disk is such that when the disk is placed 011 shoulder 2 as shown in Figure 1 the edges will abut the wall 3. Pressing the center of the disk downward into the position shown in Figure 2 causes the lower side 13 of the disk to engage shoulder 2 and the edge of the disk to be frictionally held Attaching the knob 9 t0 the disk This cap may be used by dairies instead of the ordinary paper cap. When so used,

- it is attached to the neck of the bottle so that it will not be lost. When used by the consumer on a different bottle each day, it is not attached to the bottle. The cap may be easily removed from the bottle without spattering and squirting the milk as often occurs when removing the ordinary paper cap, and may be quickly placed on the bottle to form an efiicient seal.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof, and hence I do not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is A bottle cap including a disk of curved cross-section having a conical boss; a screw having a counter-sunk head fitting within the boss, and a knob secured to the screw and engaging the upper side of the boss,

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

MICHAEL J. LYONS.
